[A new technical variation of the latex agglutination test for the diagnosis of human hydatidosis].

A new variant of the latex agglutination test using latex particles of 0,81 mu diameter is described. Hidatid cyst fluid antigen standardized by immunoelectrophoretic analysis was used. Fifty-one human sera from surgically confirmed hydatidosis and ninety control sera from non-hydatid diseases and healthy donors were studied. The method showed a sensibility of 86,2% and a global inespecificity of 1,1%. A human case of teniasis by Taenia saginata was positive. General considerations about the interpretation of results in human hydatid disease serology are made.
